The Jing Dynasty was a huge empire that appeared to be peaceful for a hundred years, but in fact suffered from internal and external troubles (separation of clans, dictatorship of foreign relatives, and frequent civil unrest).
Capital: Tianqi City.
In the middle and late period of the Jing Dynasty, Emperor Jing Hui was young and his power fell away. Dong Xiao, Duke of Jingguo, was the grand master of the dynasty and a relative of Emperor Hui's maternal clan. He actually controlled the government and military power. He was cruel and domineering. He monopolized power and had the intention of usurping the throne.
Wei Zhao's external identity: "Wei Yan", the son of the general Wei Jie. His mother died of dystocia when giving birth to twins (Wei Zhao and his younger brother Wei Yan). Wei Jie was born into a poor family and had no family background. In order to maintain the family's military power and status, he concealed his daughter's identity and lied that he only gave birth to a son "Wei Yan". His frail younger brother Wei Yan was secretly sent to Jiangnan to recuperate.
Wei Zhao was raised as a man since he was a child. He was talented in literature and military skills, and had extraordinary courage and insight. He was known as "Little Wei Jie" and had high prestige in the army.
Wei Zhao served in the army as "Wei Yan", and his sharpness attracted the attention and fear of Dong Xiao, Duke of Jingguo. Dong Xiao accidentally discovered the identity of Wei Zhao's daughter during a deliberately arranged banquet. Dong Xiao threatened the shocking secret and the lives of the entire Wei family (especially Wei Yan) and took her into the house as a concubine, intending to use her as a tool to control the Wei family and satisfy his own selfish desires. Wei Zhao was forced into the Dong Mansion, and in a cage of humiliation, using wisdom and tactics as weapons, he started a journey from a general disguised as a man to a concubine in a deep house to the supreme empress.
